[Xen-users] [PATCH] Displaying scheduler related information using xm

["Subhabrata Bhattacharya" <xions.microcosm@xxxxxxxxxxxxxx>]

Hi All,

The attached patch adds two simple scheduler related capabilities to
the xm tool.

$ xm sched-info
## Displays the name of the current scheduler (sedf/bvt)

$ xm sched-param [domid]
## If domid is supplied, then the scheduler parameters for the
corresponding domain is displayed, else scheduler parameters for all
the domains are displayed.

Example:

[root@tux06 ~]# xm sched-info
Domain Scheduler : bvt

[root@tux06 ~]# xm sched-param

Scheduler : bvt
---------------
Domain  MCuAdv  WarpBack        WarpValue       WarpL           WarpU
 0              20           80                       99           
2000000          9000000
88             20           80                       91           
2000000          9000000
90             10             0                        0  
2000000000000000 1000000000000000


The above commands will aid an administrator in monitoring and
modifying scheduler related parameters for a pool of Xen virtual
machines.

Please review and let me know your comments on this patch.

Regards, Subh
